Answer:
a=-2
b=3
Step-by-step explanation:
Solve the system of equations.
2a -5b = -19
3a + 5b = 9
Add the two equations together.
2a -5b = -19
3a + 5b = 9
------------------------
5a = -10
Divide by 5
5a/5 = -10/5
a = -2
Now we can find b
2a-5b = -19
2(-2) -5b = -19
-4 -5b = -19
Add 4 to each side
-5b = -15
Divide by -5
b = 3
a=-2
b=3
Given
2a-5b= -19 (equation1)
3a+5b = 9 (equation2)
now add both equation 1 and equation 2
2a-5b=-19
3a+5b= 9
------------------
5a = -10 (as +5b and -5b get canceled)
5a = -10
a = -2
(substitute in equation 2 or in equation 1)
3(-2)+ 5b= 9
-6 +5b =9
5b = 9+6
5b = 15
b= 3
therefore
a= -2
b= 3
verification:
2(-2)-5(3) = -19
-19 = -19
hence verified.

Answer: The train travels 50 miles per hour
Step-by-step explanation:
You already figured out the slope! The explanation is that the train travels 50 miles each hour.
The Slope Intercept form of the equation would be y=50x
If you substitute x with any number you can solve to see how much hours the train traveled.
So the train travels 50 miles per hour!
I hope this is what you needed help with!

Step-by-step explanation:
Using a standard deck of cards, a gamer drew one card and recorded its value. They continued this for a total of 100 draws. The table shows the frequency of each card drawn.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
Based on the table, what is the experimental probability that the card selected was a J, Q, or K?
A: one half
B: one third
C: 3 over 10
D: 3 over 13
Answer: its c i just took the flvs test
Step-by-step explanation:
The experimental probability that the card selected was a J, Q, or K is 1/3.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that a gamer drew one card and recorded its value.
They continued this for a total of 100 draws.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
The total number of cards drawn is 4+7+5+6+7+6+8+10+7+10+8+12+10 = 90.
The number of cards drawn that are either a J, Q, or K is 10+8+12 = 30.
Therefore, the experimental probability of drawing a J, Q, or K is:
30/90 = 1/3
Hence, the experimental probability that the card selected was a J, Q, or K is 1/3.

-What is the y-intercept of the line of best fit?
-What is the slope of the line of best fit for this scatter plot?
-What is the equation of the line of best fit?
Answer:
y-intercept : 8
slope: -1/2
equation: [tex]y = -\dfrac{1}{2}x + 8[/tex]
Step-by-step explanation:
The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)
Slope of the line can be found by the formula (y2-y1) / (x2-x1) where 9x1, y1) and (x2, y2) are two points on the line
Let's take the points (0, 8) and (10, 3) the two extreme points on the line
Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2
Equation of a line in slope intercept form is
y = mx + c
where m is the slope
b is the y intercept
The equation of the line is therefore
[tex]y = -\dfrac{1}{2}x + 8[/tex]
Answer:
Y-intercept = 8
Slope = -1/2t
Equation = y =-1/2x+8
Step-by-step explanation:
When x = 0, y = y-intercept.
Therefore, the y-intercept is 8.
We can find the slope using the formula y2-y1 / x2-x1 = m.
Let's use the points (0,8) and (4,6)
6-8 / 4-0 = m;
m = - 1/2.
Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:
y = -1/2x+8.

whats the formula for simple interest?....HELP
The formula for calculating simple interest is:
Simple Interest = (Principal x Rate x Time) / 100
Where:
Principal = the initial amount of money (the "principal sum")
Rate = the interest rate (expressed as a decimal or percentage)
Time = the length of time the interest is applied (usually in years)
It's important to note that simple interest is a method where the interest is calculated only on the original principal sum, not on any accumulated interest.
The simple interest formula is
i = P*r*t
where,
i = interestP = deposit or starting amount or loan valuer = annual interest rate in decimal formt = number of years--------------------
An example:
You borrow $500 at a simple interest rate of 2% over 3 years
P = 500r = 0.02t = 3Use those values to compute the following:
i = P*r*t
i = 500*0.02*3
i = 30
The amount of interest only is $30; meaning the total amount to pay back is $500 + $30 = $530

18) 1, because [tex]2^{4}/{2^{4} =1[/tex]. Therefore [tex]2^{4}/{2^{4} = 2^{4-4}=2^{0}=1[/tex]
Step-by-step explanation:
12) Exponent Zero rule. Anything raise to 0 power equals 1.
13) Exponent Negative rule: [tex]b^{-n} =\frac{1}{b^n}[/tex]
14) Exponent Quotient rule: [tex](a^n/a^m)=a^{n-m}[/tex]
In this case, [tex](3^3/3^5)=3^{3-5}=3^{-2}=1/3^2=1/9[/tex]
15) Exponent Product rule: [tex](a^n*a^m)=a^{n+m}[/tex]
In this case, [tex](5^8*5^{-8})=5^{8-8}=5^0=1[/tex]
16) Same rule as #15, [tex](7^2*7^{-2})=7^{2-2}=7^0=1[/tex]
17)We can work backwards here, we know [tex]2^{2} = 4[/tex] and [tex]3^{1} =3[/tex], so we need [tex]2^2/3^1=4/3[/tex].
To achieve this, use Exponent Quotient rule, what x-4=1? x=5.
Similar base: [tex](3^5/3^4)=3^{5-4}=3^{1}=1/3[/tex]. Put [tex]2^{2}[/tex] back for [tex]\frac{4}{3}[/tex]
18) 1*1*1*1=1. Anything raise to 0 power equals 1 (Exponent Zero rule). To prove this, any number(except 0) divided by itself equals 1.
Ex: 1/1=1, 4/4=1, [tex]2^4/2^4=1[/tex].
We can prove this with the Exponent Quotient rule. [tex]1=\frac{3}{3} =\frac{3^1}{3^1}=3^{1-1}=3^0=1[/tex]. No matter how I write it, it's equal to 1.
The one exception is [tex]0^{0}[/tex], which is undefined, since dividing by zero is illegal.

Tyrese wants to buy 15 packs of baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchased. Sales tax is 7%. Tyrese gives the cashier $100 to pay for his baseball cards.
How much change will he receive in return?
Answer:
$39.81
Step-by-step explanation:
$5.00 per pack
15 packs
25% discount for 10 or more packs
7% sales tax
paid $100
change?
A 25% discount means that you pay 75% of the price.
75% = 0.75
A 7% sales tax means that you pay 107% of the price.
107% = 1.07
15 × $5 × 0.75 × 1.07 = $60.19
$100 - 60.19 = $39.81
Answer: $39.81

Answer:
the answer should be B
Step-by-step explanation:
using advanced methods of taking tests and doing multiple choice I've come to realization the answer is never A and if the answer is a then you are wrong. the teachers always think that you're going to guess C so the answer will never actually be C. the last answer is D and the teacher will never make the answer D because who actually uses D. therefore using this advanced process of elimination we have cut the terms that answer should be and most definitely will be totally 100% be B.

The answer is : d (2,6,18,54,162)
the geometric sequence formula : a+ ar^1 +ar^2+ar^3+...........
where r= common ratio
the sequence is : 2,6,18,54,162
r = An/An-1 ( as per the formula)
r = 162/54 = 3
r = 54/18 = 3
lly common ratio =3
in the given options the only option d satisfies all the conditions of the geometric sequence
verification :
a= 2
ar^1 = 2*3 = 6
ar^2 = 2*9 =18
ar^3 = 2*27 = 54
ar^4 = 2*81 = 162
hence verified the sequence is 2,6,18,54,162
